Key points of detailed design of automobile traction seat structure

Lubricating oil groove: the saddle plate damage caused by poor lubrication of the saddle plate accounts for a part of the total damage of the traction seat, so the layout and depth requirements of the lubricating oil groove on the saddle plate are very important. The combination of main lubricating oil tank and auxiliary lubricating oil tank can ensure good lubrication of saddle plate.

Square box welding: when arranging the square box welding assembly, the damage of the square box welding assembly cannot be reduced by adding various vertical plates so that the entire saddle base plate is completely separated into independent small areas, because when the entire saddle plate is closed, the deformation of the square box welding assembly will not be released anywhere, and stress concentration is extremely easy to lead to fatigue damage and cracks.

Design of locking hook and pin block: the semi-trailer is connected with the traction seat through the cooperation of the traction pin and the locking hook. The traction pin is an interchangeable part of the national standard. Therefore, during the design process, the locking hook shall first meet the requirements of the national standard for the installation of the traction pin. If the design of the locking hook fails to meet the requirements of the national standard, it will directly affect the coupling of the trailer. Secondly, as important moving parts, the locking hook and the pin block should cooperate with each other in the movement process. Therefore, the contour of their mating position is very important. If this factor is not considered in the design process of the locking hook and pin block, it is possible that the locking hook and pin block may be jammed during movement.

In a word, the design of the fifth wheel assembly is an integral design involving the coordination of moving parts. Therefore, each link must be connected. This is an important part that needs continuous research and improvement and is developing towards serialization and generalization.
